Spectre Variant 4 is the new threat on the block and this not only affects Intel chips but AMD and ARM processors as well. If you are using an AMD chip then all you have to do is keep the OS up to date and you should be fine but if you are using an Intel chip then not only do you have to update the OS but the firmware as well.
Spectre Variant 4 beta patch was sent to board partners a few weeks back and only now has Asus started rolling them out. Here we have a few numbers that tell us how the performance dips after you implement the Spectre Variant 4 update. Things are very interesting indeed as we see only a minor decrease in performance, both in games and different applications.
The Intel Core i7-8700 was used for these benchmarks. The Asus ROG Strix Z370-F motherboard was used with the chip. The BIOS version 1002 was used for the tests. You can check out the numbers below:
While Intel does suggest that users will notice a performance drop of 2 to 8% these benchmarks suggest that the actual dip in performance is 1 to 3% but then again I am sure that there are applications that have not been looked into. Since December Intel CPU performance has dropped by 1 to 6% or 1 or 2 FPS. This is not much if you think about it but we would not be facing these issues if the Spectre Variant 4 threat was not there to start with.
In order to deal with the Spectre Variant 4 vulnerability, it is advised that you update your OS and BIOS as soon as you get the updates. Your motherboard manufacturer site should have the appropriate update.
Over the past couple of months, 8 new vulnerabilities have been discovered which include the next generation spectre. It is safe to say that there are more vulnerabilities but we have yet to discover them.
Let us know what you think about Spectre Variant 4 and whether or not you have been affected by the issue.
